3. Male Reproductive System
What is a vasectomy?
vas deferens (sperm duct)
epididymis
testis

4. Testes For production of male gametes (sperms)
For production of male sex hormones

5. Epididymis For temporarily storage of sperms
During copulation, muscles of epididymis contract to release sperms

6. Testis and epididymis epididymis vas deferens (sperm duct)
sperm tubules

7. Male Reproductive System
seminal vesicle
secrete seminal fluid
prostate gland
Cowper’s gland

8. Functions of Seminal Fluid
To provide a medium for the sperms to swim
To activate and nourish the sperms
To neutralize the acidity in the female reproductive tract

9. Male Reproductive System
urethra
penis

10. Female Reproductive System
oviduct
ovary
uterus
cervix
vagina

11. Functions of Ovary
For production of female gametes (ova/eggs) and production of female sex hormones

12. Oviduct Carries the ovum forward by Cick here
the beating action of the cilia on its inner surface
the contraction of muscles of oviduct
Cick here

13. Menstrual Cycle Once in about 28 days
The uterine lining becomes thickened 14 days after ovulation to prepare for the fertilized ovum to implant in it

14. Menstrual Cycle Day 28 Day 6 - 14 Day 14 - 28
Video on change in
uterine lining
Day 28
No implantation of fertilization ovum
Uterine lining breaks down; menstruation starts
Day
Lining becomes thicker with increased blood supply
Day 14 : ovulation
Day 1 - 5
Menstruation starts
Uterine lining decreases in thickness to a minimum
Day
Lining remains thick to ready for implantation of fertilized ovum

17. Hormones Hormone Male Female GnRH FSH/LH release from Ant. Pit
FSH Spermatogenesis Follicle growth
LH Testosterone Secretion Follicle release estrogen
Estrogen nd sex characteristics
Long Bone growth
General anabolic effects
Female sex drive
Skin Hydration- Increase HDL

18. Hormones Progesterone: prepares uterus for pregnancy
Testosterone: suppress LH and GnRH
male 2nd characteristics
Stimulate growth spurt
increase bone and muscle growth
libido and aggressiveness

19. Human Chorionic Gonadotropin
promotes the maintenance of the corpus luteum during the beginning of pregnancy
Progesterone secretion- maintains uterus
Maybe morning sickness
Can also be used clinically to induce ovualtion
Can be found in blood and urine
Pregnancy test
